Description

Technical Field

[0001] The utility model relates to the technical field of die-casting part processing, in particular to a deburring tooling fixture. Background Art

[0002] A die-casting part is a part formed by die casting. It uses a die-casting machine, which is a die-casting machine equipped with a casting mold. Molten metals such as copper, zinc, aluminum, or aluminum alloy heated to a liquid state are poured into the feeding port of the die-casting machine. After being die-cast by the die-casting machine, copper, zinc, aluminum parts, or aluminum alloy parts with shapes and sizes restricted by the mold are cast. Such parts are usually called die-casting parts.

[0003] After the die-casting parts are formed, several die-casting part plates are discharged by the die-casting machine. The die-casting part plates need to be knocked off with a hand-held wooden stick to form individual die-casting parts. However, burrs still exist at the edges after the die-casting parts fall off. It is necessary to remove the burrs at the edges. Therefore, a tooling fixture is needed to remove the final burrs. The product is placed on the lower mold for positioning, and oil is applied to the burr positions around. When the cutting tool of the upper mold presses down, the burrs are removed. The application of oil is to reduce the friction between the upper mold and the product and improve the service life of the upper mold. Currently, the application of oil requires manual operation by workers. Such an application method is not only relatively dangerous but also may not be applied evenly. Therefore, this application proposes a deburring tooling fixture to solve the above problems. Summary of the Utility Model

[0033] Please refer to Figure 1-2 , a deburring tooling in this embodiment includes a bottom plate 1. Above the bottom plate 1, there is a steering mechanism 2, and above the bottom plate 1, there is an oiling mechanism 4. The upper surface of the bottom plate 1 is fixed with a base 3.

The electric telescopic column 207 is fixed on the inner bottom wall of the sleeve 206.

[0036] In this embodiment, the toothed plate 204 is fixed to the outside of the output shaft of the electric push rod 202. When the electric push rod 202 is started, the toothed plate 204 slides to the right on the outside of the slide rod 203 and drives the gear 205 to rotate, so that the gear 205 drives the sleeve 206 to rotate by ninety degrees, making the connecting plate 401 located above the two lower die seats 6. The sleeve 206 is rotatably connected to the upper surface of the bottom plate 1 through a bearing.

[0037] It should be noted that an oil pump 402 is used to convey external lubricating oil to the inside of multiple connecting pipes through a connecting pipe, and the two sponge plates 404 are wetted by the multiple connecting pipes, so that the two sponge plates 404 contact the outer sides of the two die castings and are oiled. After the oiling is completed, the connecting plate 401 is moved upward and reset. At this time, the upper die 8 starts to move downward, and the burrs on the outer sides of the two die castings are scraped off, achieving the purpose of automatic oiling.

Positioning holes are formed on the lower surfaces of the four positioning cylinders 405. When the two sponge plates 404 contact the outer sides of the two die castings and are oiled, after the oiling is completed, the connecting plate 401 is moved upward and reset. At this time, the upper die 8 starts to move downward, and the burrs on the outer sides of the two die castings are scraped off. The four positioning columns 7 are respectively in clearance fit with the four positioning holes. The application of the oil is to reduce the friction between the upper die 8 and the product and improve the service life of the upper die 8.

[0040] It should be noted that when the electric push rod 202 is started, the toothed plate 204 slides to the right on the outer side of the sliding rod 203, so that the gear 205 drives the sleeve 206 to rotate by 90 degrees, and the connecting plate 401 is located above the two lower die seats 6, which can not affect the deburring work of the upper die 8 when not oiling. The application of the oil is to reduce the friction between the upper die 8 and the product and improve the service life of the upper die 8.

[0041] It is understood that where the present utility model is not described in detail, it is all well-known technology to those skilled in the art.

[0042] The working principle of the above embodiments is as follows:

[0043] (1) When the deburring tooling is needed, place the die-casting parts to be deburred outside the two lower die bases 6. Then, use the oil pump 402 to transport the external lubricating oil through the connecting pipe to the inside of the multiple communicating pipes, and use the multiple communicating pipes to wet the two sponge plates 404. Then, start the electric push rod 202 to make the toothed plate 204 slide to the right outside the sliding rod 203 and drive the gear 205 to rotate, so that the gear 205 drives the sleeve 206 to rotate 90 degrees, and the connecting plate 401 is located above the two lower die bases 6.

[0044] (2) At this time, start the electric telescopic column 207 to make the connecting plate 401 move downward, and use the four positioning cylinders 405 to be inserted into the four positioning columns 7 to achieve the purpose of positioning the connecting plate 401, and make the two sponge plates 404 contact and apply oil to the outside of the two die-casting parts. After the oil application is completed, make the connecting plate 401 move upward and reset. At this time, the upper die 8 starts to move downward and scrape the burrs on the outside of the two die-casting parts. The application of the oil liquid is to reduce the friction between the upper die 8 and the product and improve the service life of the upper die 8.
